Let's keep it simple: this tumbler doesn't leak. The silicone sipper spout has a built-in valve that stops water from flowing when no one is drinking, so it's easy for children to quench their thirst but won't make a mess if the tumbler is tipped over. It's the perfect choice for active kids, or young ones just graduating from sippy cups who aren't ready for an open-topped tumbler yet. The antimicrobial drinking spout helps prevent the spread of bacteria, so you don't have to worry when you take this travel cup on the go, and the 15-ounce plastic tumbler is lightweight and sturdy enough for everyday adventures. The materials are completely BPA free and shouldn't be microwaved—this cup is made for cold drinks. And at the end of the day, you can just disassemble the lid and spout and put everything in the top rack of the dishwasher for a quick and easy clean.
